Weight KILLS... also a stick car doesnt have any
cushion like a conv does.. I've been happy with
my 8 3/4... I ran a stock one for 600 passes and
used a trans brake all the time... it finally broke
a cap.. that was with a back brace.. I swapped over
to a alum housing that has the threw bolts... its
been in there for years now... the car is light..
but if I had a heavy car I wouldnt use a 8 3/4...
my Rampage has a 9".. thats what I had when I built it
and that has a back brace also
EDIT
the 60' has been 1.19 with this rear end.. never
slower than a 1.26
